+ - SLALIB 
+     - We tested with the Fortran version of the library; this may cause an additional step to get things to link on untested systems/compilers, as there is no one standard for how the function-names appear in the library to C code.  The default way that psLib uses is all-lower case with a trailing '_', but one may need to add to CFLAGS in src/Makefile.Globals the following:
+         - '-DFORTRAN_UNDERSCORE_PREFIX' if a '_' needs to be prefixed to the function names,
+         - '-DFORTRAN_DOUBLE_UNDERSCORE_SUFFIX' if two the names needs two trailing '_'s., and/or
+         - '-DFORTRAN_UPPERCASE' if the names appear as uppercase.
